This invention relates to a machine for making ice cream cones, and hasfor its principal object an improvement in the means for releasing bakedcones.

A further object of the present inventionlies in the provision of meansfor opening the mold sections and closing them again after the coreshave left the mold sections, but before the cones have reached thedischarge position.

Further objects of t ie invention lie in t-he specific details ofconstruction and are particularly pointed out in the claims.

In the drawings:

Figure Figure 1.

In Figure 1, the cone baking machine is of the present well known andgenerally used type, including a large wheel which supports all of themold sections between the inner ring 10 of plates and the outer ring 11of plates, these plates being bolted together and to the channel arms12, which extend radially from the main wheel in accordance withestablished practice. y

The molds are each of two half sections 111 freely slidable in guides 15on the two rings, and the half mold sections are pushed together tocomplete the mold and are withdrawn one from the other to separate the-molds by means of the crank arms 16, which extend through the plates ofthe rings 10 and 11 and carry on their outer ends the regulation cranks17, each connected by a link 18 to a stud carrier 19 movable verticallyup and down between a pair of guides 2O secured to each plate of theouter ring 11.

The two links 18 with the stud of the car- 7 is a cross section on line7--7 of rier 19 form a toggle, which is opened and closed by a track(not shown), this track raising the roller 21 on the carrier 19 to openthe molds and bearing down on the roller 21 to close the molds, theclosing of the molds being accomplished through a direct pressure of thearm 16 on the half mold sections 14: While the opening of the molds isaccomplished through a small rod 24 fast to the arms 16 and engaging apair of relatively small bars 25 secured to the top and bottom extendededges of the half mold sections.

The cores 30, the same in number as the pockets of the mold sections,preferably six, are carried on a core bar 31 bolted to the top of thecore carrier 32, each at its lower end having the customary roller (notshown) operating on a standard core operating track. I prefer to providea second roller for operating the cores and mount this roller 36 on thefree end of the core bar 31, and allow it to travel on a trackway 37adjacent the periphery of the wheel as formed by the plates 11. All ofthe structure so far described is old and has been been covered in priorap plications and patents, and no claim, there fore, is made to it inthis application save in combination with the elements about to bedescribed.

llVhen using a greater percentage of sugar in the making of the conesthan has been used in the past, the cones are found to stick to themolds, and 1 ind that VV@by slightly opening and closing the molds afterthe cores have been Withdrawn, I have relieved the stickiness to a veryconsiderable extent, and in many cases, have eliminated by this simplemeans the dificulty. 1 accomplish this desired result by a very simplemeans, namely, by the placing in the path of the roller 21 a cam toelevate the roller 1 and carrier 19 a small portion of the distancerequired to open the mold sections. rThis cam is preferably in the shapeof a small block 1() secured to a permanent and non-movable part of themachine and sloping as at 4:1 to engage the roller 21 when it is in itsdown or mold-closing position.

The roller 21 rides upwardly on this slope 4-1 and remains open for thedistance of: the

fiat portion 42 of the cam 40 and upon reaching the downwardly slopingedge 44, the mold will normally close by gravity.

In all machines upon which this device has been placed, the molds willclose of' their own accord, largely due to gravity, and somewhat due tothe jarring of the machine, these machinos normally being` of.intermittent type with a.l dwell between each of the positions usuallyin excess of 30. ln order to insure closing of the mold, however, I mayplace a small auxiliary cam 45 in the path of the roller 2l in case itis not lowered to full closing position.

In the ordinary sequence of the baking operation including the devicesust described the molds after discharge. of the baked product remainopen for one period or position, and inthis position, a safety-firstejector' passes betweenv the open molds, and insuresthat no portion ofIa baked cone remains betweenV the mold sections. At the next position,the molds close, and alter closing, a small` amount of batter isdeposited in eachv onezot the-mold cavities and at the next stageorhposition, theA cores 30 are lowered into the closed molds and thebaking operation proceeds through the'next 25 or 30 positions, orjustsolong as to give a perfectly brown andv thoroughly baked cone.. Thisbrings the cones to the position just to the right of the portion of themachine shown in Figure'l, and in the first positionshown, whichposition ,is'number 30, the molds are slightlyopen, and inl the'nextposition 31,' the molds are closed, which brings us to the final.position,. whichA as illustratedV is the thirty-,second position. Whenthe machine first arrives at this final position, the molds are closedwith the baked cones in thecavities, but these cones have alreadybeeirlooscned 'romono or both sides of the molfL in position above thisstage 32, and when the comes to rest in this position, this ai'ixiliary`core "ar is raised, but-is immediately lowered into the baked cones bymeansot a piston in. cylinder 5l. This pistonhas a rod 52 carrying aroller at the top andengages a shelf 53V on a sleeve 54 secured to avertical shaft 5G, the cylinder 5l being` mounted on a stationary partot the frame.

The auxiliary core arm 50 is provided with anV air chamber 58 incommunication by a pipe 59lwith an air-pump, causing alternate pressureand suction in the air chamber 58, which communicates with the centercavity ot each ofthe baked cones, and when the auxiliary bar 50 is inits lowered position, it rests against-the smooth plane top ot' the moldsections and presses against the excess batter which joins together thesix cones of each set or series. The preferred form oit-'this auxiliarybar is preferably in the form shown l v oy the opening of the moldsections at position in Figure 2, the bar being rectangular in crosssection anc. carrying a plurality of circular plates 60, each having anannular peripheral flange 6l rising slightly above a circular plate 62carrying a number ot perforations 63 communicating with the centralorifice G4 of the auxiliary bar and leading to the air-chamber 58. Thedisks GO are secured to the auxiliary bars 50 by any preferred means,preferably by simple screws 66,- l prefer that the circular ring orflange 6l bound by these'disks shall be ot just sufficient size toengage snugly the waste immediately at the edge of the cone proper. lnother words, l prefer that these circular ridges shall just lree thecone itself.

ln the modified form shown in Figures-3 and 4, the auxiliary bar isslightlychanged.r ln Figure 8, the bar is plane throughout its extent,save for the slight marginal flange 70, which forms a frame for themain` portion. ln this modification, the air-chamber is that portion otthe-bar bounded by the continuous flange 70, antl this flange is ofsuflicient si-Ze to receive snugly the six baked cones and just free theslight rim at the top, engaging the waste only. ln Figure 4, the bar isagain modified, this time by providingy a very largev surface to engagethe waste `and by counterboring the bar itself to provide a` recess toreceive the top edge ot the cone. ln'this modification, the air chamberis the space 74 within the counterbore. Here, again, the auxil` iary bardoes not at any time `touch the baked cones, engaging solely the wastejust surrounding the top edges of the six cones` As previouslystated,'on reachingthethirty-second position, the molds are closed. Thebar'O then'de'scendsand seats itself, no matter which modification isused, firmly on the waste, and it presses the waste against the top ofthe molds. rhe molds now by means or" well known mechanism start toopen. The baked cones are prevented from following either mold sectionby means-of the pressure exerted by the auxiliary bar 50, the frictionot' this bar against the top of the mold being always considerably inexcess-ot any-possible friction between the conc and mold. At this time,that is justbetore-the molds open, air' is withdrawn from the chamber 58through the pipe 59, and this causes the six cones toget-her with theirintegral waste usually ormed'altogether in a-single piece to stick tothe auxiliary bar 5041 as it rises by movement of the piston in cylinder5l. This cylinder-5l "is fixed', and upward movement or ythe rod 52causes upward movement of the shaft 50 and the sleeve 54, which movesupwardly with it, but whichv is formed to move angularly about theshaft. reaches its uppermost position, it is. oscillated by means of apiston within the cylinder 77, movement 'being imparted through Vapiston rod 78 having its free end pivotally con- Vhen the sleeve 54'nected as at 79 to the shelf 53. The piston 77 is secured to the shaft56 and has no movement except in connection therewith, so that movementof the piston within the cylinder 77 will cause movement through anangle of approximately 90 of the sleeve 54:. This sleeve carries a shaft80 on which the auxiliary bar is mounted, and on which it is free toturn through an angle of 3600 except as limited by other mechanism.

The auxiliary bar 50 carries an upstanding lug 90 which engages thecurved ca'm surface 91 on a bracket 92 loosely receiving the shaft 56and secured to a stationary part of the mechanism. As the sleeve 54 isrotated, the lug 90 engages the cam 91 and throws the auxiliary bar 50through an angle of 90o, changing the axes of the thereby'carried conesfrom vertical to horizontal, and

- swinging the baked cones with their Waste into the path of a series ofbrushes 9G carried on a shaft 9i' receiving motion through the belt 98.rIhese brushes remove all the waste from the cones, and at this time,the suction caused in the air chamber o8 is changed, by mechanism timedwith the molds, to pressure, and this pressure forces the six conesthrough the brushes and on to the receiving table iOO, preferably havingchannels such as lOl to receive one each of the cones of each seriesthereby stacking the cones in position to facilitate their removal tothe packaging machine. 'Ihe auxiliary bar 50 byr reverse movement of thepiston in the cylinder 77 is now restored to radial position about themolds, and by gravity is restored to vertical position as soon as thelug 90 is freed from the cam surface 91 and the parts remain in thisposition until the large wheel again comes to rest in position 32,whereupon the first movement is the lowering of the auxiliary bar 50,and with it the sleeve 54 and the cylinder 77, both of these alwaysmoving with the shaft 56.
